Non-invasive temperature transmitters

Non-Invasive temperature transmitter TSP341-N

A simpler and safer approach.

SAFER and no risk of thermowell breaking off 

REDUCED COST Quick to install for less costly installation No thermowell testing, calculations or need for exotic materials 

HIGH PERFORMANCE Keep your measurement quality 

SIMPLER Straightforward from ordering to maintenance No thermowell stocking

TSP341-N – A simpler and safer way of measuring your process temperature without the need to shut down, drill a hole or install a thermowell.

With its innovative double sensor architecture and specially developed calculation algorithm, it greatly enhances your safety and reduces your installation costs without sacrificing the quality of your measurement.
